Patent CA-2375492-C (CA)
Title: Method for controlling the profile of a non-woven lap and related production installation
Inventor: LAUNE JEAN-CHRISTOPHE
IPC: D04H1/46
Filed: 2000-05-31
Granted: 2008-10-28
Abstract: The invention concerns an installation comprising a carding machine (1), and a distributor-layer (2) depositing the card (1) web (6) in a reciprocating motion on a delivery belt (8) moving transversely. The resulting intermediate lap (16) is conveyed to a needling loom (3) to produce a consolidated lap (24). A measuring station (28) scans the consolidated lap (24) profile and transmits it to a processing unit (32) where said profile is compared to a set reference input by a terminal (33). The variations in width cause a corresponding modification in the width deposited by the distributor-layer (2) by a link (36). The local surface weight variations cause a corresponding modification of the controls applied to the carding machine (1) capable of longitudinally profiling the web (6). The invention is useful for controlling an installation for obtaining a finished product.

Title: Optical recording medium with different wobble characteristics between the user data area and the lead-out area
Inventor: LEE KYUNG-GEUN
IPC: G11B20/12
Filed: 2002-06-17
Granted: 2007-01-23
Abstract: An optical recording medium has a user data area and a lead-out area, wherein the user data area and the lead-out area each has grooves and lands formed thereon. Wobbles are formed on at least one lateral surface of grooves of the user data area and the lead-out area, and configured such that wobble characteristics are made different between the user data area and the lead-out area. Different types of wobbles are formed on the grooves of either the user data area or the lead-out area, thereby preventing an optical pickup that performs recording/reproduction from deviating from the user data area. Also, in a multi-layer optical recording medium, a whole area of a recording layer is configured to have a same condition, thereby preventing deterioration in reproduction and/or recording due to a difference in light power transmittance of another recording layer.

Granted: 2010-08-24
Abstract: L'invention concerne une tige de cathéter utilisant du polytétrafluoréthylène perfluoroalcoxy (PFA) comme revêtement lubrifiant de la lumière interne qui facilite l'avancement de dispositifs médicaux supplémentaires. Le PFA a un pouvoir lubrifiant adéquat et ne nécessite pas de techniques de fabrication spéciales. De cette manière, on peut traiter le PFA par des techniques traditionnelles d'extrusion de matière moulée et par injection, compression, transfert par rotation et moulage par soufflage; on peut optimiser la capacité de traitement de la lumière interne lubrifiante. En outre, la tige de cathéter comprend des parties d'un élément tubulaire externe modifié par procédé d'ablation. Le procédé d'ablation permet de retirer de façon sélective la matière polymère extrudée autour et entre les contours d'une couche de support tressée. Dans un mode de réalisation d'exemple, une partie de la couche externe du cathéter est enlevée par ablation au laser puis remplie de nouveau au moyen d'inserts polymères présentant des caractéristiques de souplesse différentes.

Title: Adjustable dispersion compensator with few mode fibers and switchable mode converters
Inventor: RAMACHANDRAN SIDDHARTH
IPC: H04B10/02
Filed: 2003-08-19
Granted: 2011-10-25
Abstract: The specification describes dispersion compensators that are adjustable based on selection of mode propagation properties of two or more modes. The fundamental device structure comprises two or more sections of optical fiber that support the fundamental mode as well as well as one or more higher-order-modes (HOM). The HOM fibers are connected to each other by means of a spatial mode-converter (MC) that is switchable. The MC may be fabricated with, for example, long-period fiber-gratings (LPG), coupled waveguide devices, free-space phase-retardation elements, micro-electro-mechanical devices, or acousto-optic couplers. The MC is assembled such that it transforms any incoming spatial mode into one of any other guided modes in the HOM fiber. Switching is achieved by strain, temperature, the electro-optic or nonlinear optic effect, or any other physical effect that changes the refractive index of the optical material used to construct the MC.

Abstract: L'invention concerne un panneau en verre acrylique destiné à être employé en tant qu'élément antibruit non transparent dans des murs antibruit. Ledit panneau présente une taille de 2 x 2 m ou plus, et une épaisseur supérieure à 8 mm, de préférence supérieure à 12 mm. Des fils, des bandes, des grillages ou des réseaux réalisés dans un matériau incompatible avec le verre acrylique sont intégrés dans ledit verre acrylique afin de lier les éclats en cas de rupture des panneaux, et ledit panneau présente une teneur de 40 à 80 % en poids de charges par rapport à son poids total (sans tenir compte des fils, bandes, grillages ou réseaux intégrés). Lesdites charges sont de préférence des extendeurs en talc et dolomite de préférence mélangés à de l'hydroxyde d'aluminium. L'invention concerne également un procédé de fabrication de tels panneaux. Les panneaux en verre acrylique selon l'invention, présentant une forte teneur en charges, constituent une alternative économique à d'autres matériaux non transparents, peuvent être aisément combinés à des panneaux antibruit en verre acrylique transparents, et permettent du fait de leur densité de surface élevée, un degré de réduction sonore suffisant, malgré une épaisseur réduite. Par ailleurs, lesdits panneaux permettent l'utilisation de systèmes liant les éclats, tels que des fils de nylon ou d'acier, et appartiennent à la classe B2 en matière de tenue au feu, même à la classe B1 lorsque de l'hydroxyde d'aluminium est employé en tant que charge.
